绝对音高的知觉-认知机制和相关的神经机制尚不完全清楚。这项fMRI研究的目的是通过音高记忆实验来检查AP背后的神经网络，并将两组音乐家进行对比，一组有AP，另一组没有AP。我们发现两组的共同激活模式包括颞上回（STG）延伸到邻近的颞上沟（STS），顶叶下小叶（IPL）延伸到邻近的顶叶内沟（IPS），额下回（IFG）的后部，前辅助运动区（sma前）和小脑外侧上区。在音高记忆任务的早期编码阶段，左STS （AP乐手激活较多），在音高记忆任务的早期知觉阶段（ITP 0-3）和后期工作记忆/多模态编码阶段，右顶叶上小叶/顶叶内沟（IPS）（非AP乐手激活较多），组间差异显著。后侧IFG （AP音乐家更多）和IPL（非AP组更多的前侧激活，AP组更多的后侧激活）组间趋势不显著。由于在早期知觉编码阶段观察到AP音乐家左STS的激活增加，并且STS已被证明参与分类任务，其激活可能表明AP音乐家在音调任务中涉及分类区域。非ap音乐家的右SPL/IPS激活增加表明，要么是音调工作记忆（WM）网络部分区域的使用增加，要么是使用多模态编码策略，如使用视觉空间映射方案（即，想象五线谱上的音符或使用相对音高的空间编码）来获取音高信息。
The perceptual-cognitive mechanisms and neural correlates of Absolute Pitch (AP) are not fully understood. The aim of this fMRI study was to examine the neural network underlying AP using a pitch memory experiment and contrasting two groups of musicians with each other, those that have AP and those that do not. We found a common activation pattern for both groups that included the superior temporal gyrus (STG) extending into the adjacent superior temporal sulcus (STS), the inferior parietal lobule (IPL) extending into the adjacent intraparietal sulcus (IPS), the posterior part of the inferior frontal gyrus (IFG), the pre-supplementary motor area (pre-SMA), and superior lateral cerebellar regions. Significant between-group differences were seen in the left STS during the early encoding phase of the pitch memory task (more activation in AP musicians) and in the right superior parietal lobule (SPL)/intraparietal sulcus (IPS) during the early perceptual phase (ITP 0–3) and later working memory/multimodal encoding phase of the pitch memory task (more activation in non-AP musicians). Non-significant between-group trends were seen in the posterior IFG (more in AP musicians) and the IPL (more anterior activations in the non-AP group and more posterior activations in the AP group). Since the increased activation of the left STS in AP musicians was observed during the early perceptual encoding phase and since the STS has been shown to be involved in categorization tasks, its activation might suggest that AP musicians involve categorization regions in tonal tasks. The increased activation of the right SPL/IPS in non-AP musicians indicates either an increased use of regions that are part of a tonal working memory (WM) network, or the use of a multimodal encoding strategy such as the utilization of a visual-spatial mapping scheme (i.e., imagining notes on a staff or using a spatial coding for their relative pitch height) for pitch information.
